Description
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a device for automatic detection
of battery polarity, and more particularly to a device wherein
positive terminals and negative terminals of battery electrical
connecting units are respectively connected to detector terminals
of a detector circuit.
(b) Description of the Prior Art
FIG. 1 shows a charger A of prior art, wherein disposition of
electrical contact points A1 of the charger A is fixed, and
positive contact points and negative contact points extending from
a circuit located interior of the charger A are fixed contact
points. If a battery is disposed into the charger A having a
dissimilar configuration of positive and negative contact points,
then the charger A is unable to implement charging of the battery,
even to the extent of posing a threat of damaging the battery.
Furthermore, because of different sizes of batteries and position
and spacing of electrical contact points of chargers are all
unequal, thus, the single charger A is only able to singly
accommodate the corresponding battery A2, and is unable to achieve
accommodating diverse batteries to implement charging thereof.

battery polarity, and more particularly to a device wherein

connecting units are respectively connected to detector terminals

circuit actuate a connection with positive voltage electrical
connecting units and negative voltage electrical connecting units,
thereby enabling the detector circuit to form a complete
circuit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention provides a device for automatic detection of
battery polarity. Referring to FIGS. 2 and 3, wherein a detector
circuit C is structured to comprise detector terminals D, detector
units E, positive voltage electrical connecting units F and
negative voltage electrical connecting units G.
Operational procedure for using the present invention involves
first connecting battery electrical conducting units H with the
detector terminals D of the detector circuit C. When the detector
terminals D are connected to positive poles of a battery B1, then
one set or more than one set of detector units E detect positive
voltage, which actuate an electrical connection with the positive
voltage electrical connecting units F, and positive poles of a
charger device B are presented to the detector terminals D and
electrically connected to the positive poles of the battery B1.
Correspondingly, when the other detector terminals D are connected
to the battery B1, the remaining detector units E determine that
they are negative voltage and actuate the negative voltage
electrical connecting units G, then negative poles of the charger
device B are presented to the detector terminals D and electrically
connected to the negative poles of the battery B1, thereby forming
a complete charge circuit that enables the charger device B to
commence charging the battery B1.
Referring to FIGS. 3, 4 and 5, which show embodiments of the device
for automatic detection of battery polarity of the present
invention, wherein when the battery electrical conducting units H
are connected to the detector terminals D of the detector circuit
C, hen positive terminals H1 and negative terminals H2 of the
battery electric conducting units H need only electrical connect to
any two terminals of the detector terminals D to enable the
detector circuit C to form a complete charge circuit.
A charger I uses two or more than two detector terminals D to
enable accommodating batteries B1 of different sizes and match
different positions and spacings of the battery electrical
conducting units H, thereby achieving electrical connections with
all charge contact points of the battery B1, and enabling the
charger I to accommodate the different types of battery B1 and
correctly locate the positive terminals H1 and the negative
terminals H2 of the battery electrical connecting units H.
If detector terminal A points D1 are electrically connected to the
positive terminals H1 of the battery electrical conducting units H,
then positive potential passes through the detector units E, which
detect and output positive voltage that enables electrical
connecting with the positive voltage electrical connecting units F,
thus, the positive voltage electrical connecting units F enable
electrically connecting positive poles of the charger device B to
the detector terminal A points D1, thereby enabling the positive
poles of the charger device B to connect to the positive terminals
H1 of the battery electrical conducting units H. Correspondingly,
detector terminal B points D2 are electrically connected to the
negative terminals H2 of the battery electrical conducting units
H1, and negative potential passes through the detector units E,
which detect and output negative voltage that enables electrical
connecting with the negative voltage electrical connecting units G,
thus, the negative voltage electrical connecting units G enable
electrically connecting negative poles of the charger device B to
the detector terminal B points D2, thereby enabling the negative
poles of the charger device B to connect to the negative terminals
H2 of the battery electrical conducting units H, and enabling the
charger device B to commence charging of the battery B1.
Conversely, if the detector terminal A points D1 are electrically
connected to the negative terminals H2 of the battery electrical
conducting units H1, then negative potential passes through the
detector units E, which detect and output negative voltage that
enables electrical connecting with the negative voltage electrical
connecting units G, thus, the negative voltage electrical
connecting units G enable electrically connecting the negative
poles of the charger device B to the detector terminal A points D1,
thereby enabling the negative poles of the charger device B to
connect to the negative terminals H2 of the battery electrical
conducting units H. Correspondingly, detector terminal B points D2
are electrically connected to the positive terminals H1 of the
battery electrical conducting units H, and positive potential
passes through the detector units E, which detect and output
positive voltage that enables electrical connecting with the
positive voltage electrical connecting units F, thus, the positive
voltage electrical connecting units F enable electrically
connecting the positive poles of the charger device B to the
detector terminal B points D2, thereby enabling the positive poles
of the charger device B to connect to the positive terminals H1 of
the battery electrical conducting units H, and enabling the charger
device B to commence charging of the battery B1.
If detector terminal C points D3 are not electrically connected to
the positive terminals H1 nor to the negative terminals H2 of the
battery electrical conducting units H, then the detector units E
detect and output zero voltage, and the zero voltage is unable is
effect electrical connection with the positive voltage electrical
connecting units F and the negative voltage electrical connecting
units G, thus, a charge circuit is unable to be formed.

practicability of the present invention, advantages of the present
invention are described hereinafter:
